Abstract
The utility model discloses a hinge type excavator chassis, comprising a machine frame I(11), a machine frame II(12), a hinge shaft (13), a steering cylinder (14), a front axle (15), a rear axle (16), etc. The machine frame I(11) and the machine frame II(12) are hinged together by the hinge shaft (13); both ends of the steering cylinder (14) are respectively hinged with the machine frame I(11) and the machine frame II(12). A front axle (14) and a rear axle (15) are respectively mounted on the machine frame I(11) and the machine frame II(12). The utility model can realize hinged steering and is characterized in simple structure and small turn radius.
Description
One. affiliated field
The utility model is a kind of radial type chassis of dredging machine, and specifically a kind of wheeled excavator of articulation steering of realizing is used the chassis.
Two. background technology:
At present, the wheeled excavator of domestic use is monolithic with the frame on chassis, and propons is that steering and driving axle, back axle are common drive axle.The chassis turning radius of front-wheel steer is big, and the front and back bridge is not general, the steering and driving axle complex structure.
Three. summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this utility model provides a kind of front and back bridge all can use common drive axle, simple in structure, the radial type chassis of dredging machine that turning radius is little.
Design scheme of the present utility model is: the utility model has designed a kind of radial type chassis of dredging machine, by frame I, frame II, jointed shaft, turn to oil cylinder, propons, back axle etc. to form.Frame I is a framework that has hinged seat, and frame II is a framework that has hinged seat, turntable mount pad, and turning to oil cylinder is double acting hydraulic cylinder, and propons, back axle are the common drive axle of not being with transfer.Frame I, frame II are hinged to one with jointed shaft, and propons, back axle are installed in respectively on frame I, the frame II, the two ends that turn to oil cylinder respectively with frame I, frame II hinge-coupled, turn to oil cylinder to be communicated with the hydraulic steering gear of excavator.
When the utility model travels, turn to the piston rod of oil cylinder to stretch out during the left-right rotation steering wheel or withdraw, promote frame I, frame II and relatively rotate, realize articulation steering, have littler turning radius than front-wheel steer around jointed shaft.
Therefore bridge all can use common drive axle before and after the utility model, has characteristics such as simple in structure, that turning radius is little.
Four. description of drawings
Accompanying drawing is the schematic diagram of an embodiment of the present utility model.
Five. specific embodiments
Accompanying drawing is an embodiment of the present utility model, by accompanying drawing as seen, the utility model by frame I (11), frame II (12), jointed shaft (13), turn to oil cylinder (14), propons (15), back axle (16) etc. to form.Frame I (11) be one have hinged seat, turn to cylinder support, the framework of preceding bridge seat, frame II (12) be one have hinged seat, turn to cylinder support, the framework of back bridge seat and turntable mount pad, turning to oil cylinder (14) is double acting hydraulic cylinder, and propons (14), back axle (15) are the common drive axle of not being with transfer.Frame I (11), frame II (12) are hinged to one with jointed shaft (13), the two ends that turn to oil cylinder (14) respectively with frame I (11), frame II (12) hinge-coupled, propons (14), back axle (15) are installed in respectively on frame I (11), the frame II (12), turn to the hydraulic fluid port of oil cylinder (14) to be communicated with the hydraulic steering gear hydraulic fluid port of excavator.
When the utility model travels, turn to the piston rod of oil cylinder (14) to stretch out during the left-right rotation steering wheel or withdraw, promote frame I (11), frame II (12) and relatively rotate, realize articulation steering, have littler turning radius than front-wheel steer around jointed shaft (13).
Therefore the utility model front-rear axle all can use common drive axle, have simple in structure, turn to The characteristics such as curved radius is little.
Claims (1)
